Re-send column value w/ onupdate default during post-update

Adjusted the behavior of post_update such that if a column with
an "onupdate" default has received an explicit value for
INSERT, re-send the same data during a post-update UPDATE so
that the value remains in effect, rather than an onupdate
overwriting it.
